Abstract:
Curuba is native of Andean South America, specially Colombia.
This country has some 2 500 ha in the provinces of Boyaca, Cundinamarca, Santanderes, Nariño, Antioquia and Valle, with a small plot production of 7 t/ha/y.
With a good technical level production can rise to 25 to 30 t/ha/y.
Curuba is cultivated between 2 000 and 3 000 m above sea level in loamy clay soils and loamy sandy soils at frost-free temperatures between 14 and 15°C and a relative humidity of between 70% and 80%. Different support systems are used in different regions such as arbour (emparrado), spalier with 1 or 3 metallic threads, mixt arbour and single or mixt T.
Given its alogamous condition and mainly the multiplication through seed, especies vary greatly.
However, most explotations is based on Passiflora mollisima or Castillian curuba. Passiflora tripartita var. mollisima, or quitenian curuba; Chilean or red Passiflora cumbalensis and another one called indian are also commercially grown.
Importants problems yet to be solved are the development of antracnosis resistant varieties and industrialization of curuba pulp.
